If the user performs a tuning attempt without explicitly calling the
s_std ioctl(), a value of zero is sent from tuner-core to xc5000. This
causes the xc5000 driver to leave the standard unchanged. The problem
was masked by the fact that the xc5000 driver defaulted to NTSC, but if
you happened to perform an ATSC/ClearQAM tuning attempt and then do an
analog tune, the net effect is an analog tune with the standard still
set to DTV6.
Keep track of whether the standard has ever been sent to tuner-core. We
don't make an s_std subdev call explicitly during probe because that
will cause a firmware load (which is very time consuming on the 950q).
With the logic in this patch, the s_std call will occur automatically on
the s_freq call if it hasn't already been set.

In some cases users would see the xc5000_attach() call failing for the
digital side of the tuner on initialization. This is because of udev
running v4l-id while the digital side of the board is still coming up.
This is the exact same race condition which was present in em28xx (not
surprising since I copied all the locking logic from that driver when I
added analog support). Reproduce Mauro's fix from the em28xx driver in
au0828.

The g_reg and s_reg calls worked properly if acting on subdev registers
(such as the au8522), but didn't work against the au0828 itself. Copy

There is an apparent bug in the au8522 TS clocking which can result in
it delivering a TS payload to the au0828 that is shifted by some number
of bits. For example, the device will announce a packet containing "FA
38 FF F8" which if you shift left one bit is "1F 47 1F FF F0..."
This presents itself as no TS stream being delivered from the kernel to
userland, since the kernel demux will drop every packet.
In the event that this condition occurs, restart the DVB stream.
Also, this patch includes a couple of lines of cleanup to not change the
FIFO configuration while the FIFO is running (which can screw up the
state machine), and dequeue the buffers before turning off the FIFO.
This puts the logic in sync with the Windows driver.

The table of valid SNR values for QAM 256 is off by one, and as a result
if the SNR is oscillating between 40.0 and 39.9 dB, tools like azap show
it going back and forth between 40.0 and 0 (misleading some people,
including myself, to think signal lock is being lost or there is a
problem with register reads).
Fix the table so that 40.0 dB is properly represented.

It turns up the autodetection for the video standard in the au8522 is
prone to hanging the chip until a reset is performed. This condition is
trivial to reproduce simply by tuning to a station and then rapidly
unplugging/ replugging the coax feed.
Because we've never claimed to support anything other than NTSC-M, just
disable the video-standard autodetection logic and force it to always be
NTSC-M.

The dvb-usb-v2 core doesn't know anything about CI. So, the
driver needs to handle it by hand. This patch stops CI just
before stopping URB's/RC, and restarts it before URB/RC start.
It should be noticed that suspend/resume is not yet working properly,
as the PM model requires the implementation of reset_resume:
dvb_usb_az6007 1-6:1.0: no reset_resume for driver dvb_usb_az6007?
But this is not implemented there at dvb-usb-v2 yet.

Some video decoders such as tvp5150 provide separate
video fields (V4L2_FIELD_SEQ_TB/BT). This driver uses
dmaengine to convert this format to V4L2_FIELD_INTERLACED_TB/BT
(weaving) or V4L2_FIELD_NONE (line doubling) so that the
image can be displayed or processed.
Of course there will be combing effect in the image but this
